SUMMARY

OF UNIT 1 OPERATING EXPERIENCE - JANUARY 1981 1/1 At the beginning of this reporting period, Unit I was shutdown for repair of the main turbine thrust runner.

1/7 Completed filling the Reactor Coolant System (RCS) at 0235.

1/9 Reactor Coolant System (RCS) heatup completed at 1000.

1/10 The reactor was brought critical at 1355.

1/11 The unit was paralleled at 1412 and commenced increasing power to 50%. Increased load to 390 MWe at 2030.

1/14 Completed 50% plateau physics testing at 2110.

Started increasing load tv 90%.

1/15 At 0845 the power increase was halted at 68% to repair #12 Steam Generator Feed Pump speed controller. Recommenced power increase at 1800 1/16 At 1110 the reactor tripped on low steam generator level when

1. 12 ' feedwater regulating valve closed.

The reactor was brought critical at 1914.

1/17 The unit was paralleled at 1205.

1/13 Load was increased to 335 MWe at 2220.

SUMMARY

OF UNIT 1 OPERATING EXPERIENCE - JANUARY 1981 CON'T 1/19 Increased load to 880 MWE at 2000.

1/23 Load was increased to capacity (910 MWe) at 1300.

1/25 At 0500 load was reduced to 815 MWe to investigate saltwater leakage into the mah condenser. Increased load to capacity (910 Mwe) at 1730 tfter plugging I condeaer tube.

-1/31 At 2340 load was decreased to 700 MWe for main turbine control valve testing. At the end of this reporting period Unit I was operating at 700 MWe with the reactor at 77% power, while testing main turbine control valves.

i-l i

SUMMARY

OF UNIT 2 OPERATING EXPERIENCE - JANUARY 1981 1/1 At the beginning of this reporting period Unit 2 was operating at 520 MWe with the reactor at 57% power being limited by the power coastdown procedure.

1/17 The unit was taken off the line at 1520 and the reactor was shutdown at 1620 for the 3rd scheduled refueling outage.

1/18 The reactor was placed in cold shutdown at 1330.

1/20 Completed draining the Reactor Coolant System (RCS) at 0925.

1/31 At the end of this reporting period Unit 2 was shutdown for its 3rd scheduled refueling outage.
